I've placed a 45mp TIFF file here if folks would like to load that one up to see how it behaves on your system. It's somewhat bigger than a D800 file, being 45mp, so if you can deal with this one you should have no trouble dealing with a D800 file. There is no creative art involved in this image!
Someone also made the point that doing panos of these files will make greater demands - that is absolutely true. Loading up a bunch of 36mp files to do a 6-wide pano is not going to happen on a 4GB machine. (Neither does doing that with 12mp files, for that matter. I tried it.)
